what I deduce from just the last patch I would guess so. He misused :-) 
output_active to trigger error and drop extra tokens and therefore moved

end_token_list; {conserve stack space in case more outputs are  triggered}

earlier, but that then also dropped the aftergroup tokens in all cases.

so yes, using its own boolean looks much safer.


Incidentally, your test file that you appended is a bit odd because it 
does \aftergroup on "s" and then typeset "hould-appear" in the output 
routine so that it would generate "hould-appears"

Not exactly wrong but perhaps surprising to somebody down the road.

Perhaps better

\def\xxx{\aftergroup\yyy}
\def\yyy{\message{message should show up}}

by the way how do you test such -ini tests automatically?
